FILTER-CLEANING DEVICE.

11 '0 all whomit may concern:

Be it known that I, HEaBEn'r N. KILBY, a citizen ,of the United States, residing at Cleveland, in the county of Cuyahcga and State .of-Ohio, have invented certain new .and useful Improvements in Filter-Cleaning Deviee's, of which the following isa. specification}; v i j I My'invention relates to filter cleaning de- .types of filterswherein pulp is designed to I v be separated from the juices, but has special application'to those/filters associated with the'sugar industry.

In-filtering various posit isausually left upon the various filter elements and at times, .depending upon the liquid being filtered, this cake or deposit is of a gummymature. This residue then notonly stops up the pores for permitting the ready'filtering of the liquid, but it is alsosomewhat difiicult. of removal.

invention contemplatesthe provision ng structure whereby this cake or a). be readily removed. In this pniieitidiiimyinvention' also resides in so i -ar anging the '"'vario1is [parts that the remfoval f this cakeimay be effected without ch ngingithe-norma.l relative arrangement of 'the filter plates themselves with respect toeach other.

Another object of my invention resides in the provision of peculiarly novel means ion's praying the various filter plates with streams of water, this water being directed by'ineans of a structurewhereby the streams themselves may be given such movementto play over the entire filtering surfaces.

My invention also resides in the combinationof a plurality of cleaning devices-so arranged to have cleaning movement over the various filter plates and means for 'infiating the filter -elements themselves,

.fwhere these elements are of an inflatable na-- ture, whereby they, are p ufl'ed'out. to moi ereadily facilitate the cleaning operation,

Still a further object of. my invention resides in the provision'of means whereby" the interior of all of the filter elements may be slushed or-cleaned whenever desired.

Anothe object resides in the peculiar t'yp e wherein this cleaning member isof it hollow with a rota tahly mounted \va'ter'supply pi pe,

resent the preferred embodiment of my invention.

In these drawings, similar characters of reference designate corresponding parts, vices and has [general application .to all and, Figure 1 shows my device as applied to a well known type of filter, the structure being shown in perspective, Fig. .2 is a detail view in perspective done of the filter elements and its connections, Fig. 3 is a view in cross section through the structure shown in Fig. 1,Fig. 4. is a top plan .view of a'portion of the structure shown in Fig. 3, the- 1ncl0s1ng hood being shown in section,'Fig.

5 is a detail view in perspective of a portion of one cleaner element, and, Fig-J6 is a de tail view of one formpf pipe connection used by me. i

In these drawings, 1 representsv aback plate provided with a horizontally extending depressed portion 1", the various filter elements 2 being preferably vertically disposed and supported from this back plate, which in turn is supported upon end standards The filters 2 are provided inany desired number and are all slightly spaced with respect to each other, being formed of a general outer framework 4' carrying a plurality of vertically disposed cross members 5 at suitable intervals, the members4 terminating at their upper and lower ends, as shown at 6, to form a means of attachment to the back plate. Over the framework of each filter element is placed a fabric covering 7 of any preferred type, which allows the juices to enter the interior'of the various filter elements and discharge them through the valve controlled outlet pipe, as

shown at 8, each. of ttie pipes 8 being in yguices to be filtered, enter the casing structure through the inlet shown at 11 and by of brush or cleaning member used-bym'e internal pre$ure within the casing, they filter through the various filter elements and nature carrl'ed by and in communicationv then pass out through the outlet pipes 8,

leaving 'whatever solid matter they may i contain in the nature of a deposit, uponthe All of the filter elements complished very readily, I have provided a pipe 12 located in the upper corner of the depressed portion 1 of the back plate and extending the full lengthof the arrangc.

ment of filter plates. This pipe is rotatably supported in any desired manner and 1s located in the depressed portion 1 in order that the hood member 9 may be readily swung about its pivot point without'interticularly plain in Figs. 4 and 6, this pipe connects with a service pipe 13 by means of the packed union designated generally at 14' whereby the portion 1.2 is rotatable and still maintains its communicationwith the pipe 13. This pipe 12 is provided at repeated intervals betweenthe various filter elements with a member 15 ofthebrush or squeegee type as is shown in Fig.5, from which it will be seen that the brush itself carries a plurality of bristles16 and is held, as shown at 17, to be in communication with the water pipe 12 through the apertures shown at 18. Also, each brush member is provided with a longitudinally arranged series of outlet apertures 19, from which it will be apparent that rotary movement of the pipe 12 will cause a spraying of water over the -surfaces of the various filter elements by means of the mechanism just described.

Preferably, mechanism is provided whereby this spraying action may be accomplished mechanically rather than-by manual opera tic-n, and this mechanism I have shown as comprising an operating rod 2.0-rigidlycarried by ,the'pipe 12 at each'end outside of the back rods being provided with a laterally pro jecting' pin 21. -Each of these pins is designed to operate within theslotted portion 22 of the operating head 23 carried upon one end of the piston shown at 24. Each of the pistons 24 is slidably mounted in the bearing member shown at 25 and is pivotally connected through the medium of a connecting link 26 with an operating crank 27 rigidly carried upon the operating shaft 28, this latter receiving its rotary motion, by

means. of a pulley 29 deriving power from .any desired source. It will thus he apparent that rotation of the shaft 28 will impart an oscillatory movement to the. water pipe 12 through the pin and slot connection shown-at 21 and 22, whereby the sprays or streams passing through the, apertures 19in each of the brush members 15 may be di rected over the entire filtering surfaces of the various filter elements, it being understood that the hocd 9 hasjbeen previously elevated to expose all of the filter elements to view. Further, by the provision of the bristles 16, the filtering surfaces of each of ;slushing their'inteiior, I have provided a -fserie s of inlet connections 30, to each; of the .Qfilter elements and fering with its operation. As is shown parl .ments and will, therefore, make the-scrubplate 1, each of these operating the cleaning and scrubbing of theexterior of each of the filter elements, as well as also cleaning or nunicate with valve controlled supplyand freturnpipes 32 and 33 respectively, whereby 1t w ll be apparent that by closing the outlet pipe 33, each of thefilter-elements may be inflated with anyconvenient fluid at hand. This'inflation will cause'a pulling outof the cloths usually surrounding ',the' filter ele-.3 5

hing action more etl'ectivei In case it'is then desired to slush the interiloi'vbf the filter elements, the valve control of thejoutlet pipe a 33 maybe opened to'allow afree circulation 9 of the cleaning fluid through each of the filter elements, it being understood that the juice outlets 8 are all preferably closed during this operation.

By the structure just described, the-cloths '95 forming a portion of the-various filter ,eler ments may be bulged outwardly. to insure more perfect contactbetween thegcleaning structures as they are given movementover the filter surfaces. Further,-it will; be ia'p f-joo parent that I. have provided a structure whereby these filter plates mayi .b1e very effectively cleaned both 'interiorly and exteriorly, no matter what the nature of the de-' 7 I posit or juice may. be.

:AlSO by the peculiar 0.5 location of the water spraying and cleaning structure in the upper portioniof the depressed portion 1 of the back platel, the housing may be elevated tofexp'os'e the entire surface of the various "-filter elements to What I claim, is: y I 1.
